Rinse the salmon fillet with lemon and cold water; pat dry with paper towel.
Marinate the salmon fillet with 1/2 tablespoon of oil, lemon juice and black pepper.
At 350 degree, broil the salmon for 15 minutes; keep it outside first; at room temperature, place it in the fridge.
Meanwhile, boil water, add the pasta, cook it for 15 minutes or al dente; rinse in cold water and drain; keep it in fridge.
Prepare the salad dressing - mix the oil, vinaigrette or wine, Oregano or thyme, scallions, the sour cream, black pepper and salt; whisk it well.
Add the salad dressing to the pasta; toss well until the pasta is well covered.
Break the broiled salmon fillet into small pieces; combine fillet pieces with the pasta salad.
On a serving platter, place the salmon-pasta salad and sprinkle parsley. Serve it cold. Keep in fridge.
